I’ve been experimenting with using a brush pen and and an ink pen in the same drawing. It creates some wonderful markmaking contrasts right off the bat that I love. Pentel makes a relatively inexpensive brush pen called a pocket brush pen that has a seductive, responsive feel. I have a number of different sizes and colors of the Pigma Micron archival ink pens that I’ve been using as my go-to pens for sketching. This drawing paired the Pentel brush pen with a .03 ink pen.
